# Foreman::Helpers

### Public Instance Methods

classify(dashed_word) click to toggle source

Given a word with dashes, returns a camel cased version of it.

classify(‘job-name’) # => ‘JobName’

    # File lib/foreman/helpers.rb, line 7
    def classify(dashed_word)
      dashed_word.split('-').each { |part| part[0] = part[0].chr.upcase }.join
    end

constantize(camel_cased_word) click to toggle source

constantize(“Module”) # => Module constantize(“Test::Unit”) # => Test::Unit

The name is assumed to be the one of a top-level constant, no matter whether it starts with “::” or not. No lexical context is taken into account:

C = ‘outside’ module M

    C = 'inside'
    C # => 'inside'
    constantize("C") # => 'outside', same as ::C

end

NameError is raised when the constant is unknown.

    # File lib/foreman/helpers.rb, line 27
    def constantize(camel_cased_word)
      camel_cased_word = camel_cased_word.to_s

      names = camel_cased_word.split('::')
      names.shift if names.empty? || names.first.empty?

      constant = Object
      names.each do |name|
        args = Module.method(:const_get).arity != 1 ? [false] : []

        if constant.const_defined?(name, *args)
          constant = constant.const_get(name)
        else
          constant = constant.const_missing(name)
        end
      end
      constant
    end
